Looks like a pretty serious mold issue. Nealtw hit the nail on the head advising you to dry the area out. I would also recommend calling in a mold inspection so that you can get a protocol on the extent of the mold, and what should be corrected to make sure the mold doesn't come back. Are you or your family experiencing any symptoms of mold exposure? Notice any odor that smells like mildew?

Snellexperts, had a local guy put a drain pipe around the inside of the crawl space and install a sump pump to keep the water out. There are drainage issues in the back of the property, which are going to be tough to fix, so went with the sump pump and vapor barrier.

I did spread around some borax in the space prior to him showing up and attempted to bag an remove what I saw. Haven't been down there in a couple day, but going there today with some boric acid mixed with water. If you have a suggestion for a parts per mix, please pass it along. Also very open to any additional suggestions on killing this stuff and making the house safe.

The house is a vacant house that I've been trying to fix up to sell for quite a while. No one is living there now. Found out I bit off more than I can chew, that's for certain. As I mentioned in my first post, I was under the house two weeks prior to the pictures you see and there was nothing growing down there. I had removed part o the old vapor barrier, but didn't put the new section back down which left part of the ground exposed for a couple weeks. Scary how fast whatever it is grew when a little water was added.

By just adding the vaper barrier and not taking the time to correct the problums causing it or at least raising the inside grade it may that all you did was add a pool liner.

Haven't used that stuff in a while. We switched over to a "green" product thats completely safe cuz it's made from plant extract. Let me check when I get in the office tomorrow and I will get back to you if you still need that info.

SnellExperts, would appreciate any information you can provide. I have already removed what I could and treated with borax and boric acid (two different times), but thinking I probably missed some. I did put down a vapor barrier and had a guy dig out a sump pump with a drain channel around the entire inside of the crawl space, so hopefully I'm on my way to solving the problem.

With a drain inside the crawl space, this house will always have a moisture issue, you may want to look at a venting system like the one I have posted here.

Neal,
What's Comdensation?

How's the drain going to cause them to have moisture problems?

Most times the water is kept out of the crawl space with outside drainage. With this system inside there is a steady supply of water in the crawl space. In warmer weather you will have evaporation. when the weather changes to cool or cold that moisture will condence on cold water pipes, framing members that a exposed to the cold outside like the sill sitting on the foundation. A good supply of air is a cheap way to keep the crawl space and the house healthy.

It looks like mold to me, especially since your talking about all the rain involved. I've seen black mold before, and it isn't pretty!
